The Roland D-70 "Super LA Synthesizer" was released as a successor to the iconic D-50. While the D-50 relied heavily on the interplay between synthesized "partials" and PCM samples, the D-70 shifted toward a fully PCM-based architecture, utilizing the U-110/U-220 series waveforms but with the addition of a powerful digital filter and effects section.

The SoundFont versions are often "too clean." The D-70 had a specific sample rate and DAC coloration that is lost when converting to a modern 32-bit float SF2 file. However, for modern production, the "cleaner" SF2 version is often preferred for layering.

The Roland D-70, released in 1990, remains a cult favorite for its unique "Super LA" synthesis and lush, cinematic textures. While often overshadowed by the D-50 or the JV series, its distinctive "DLM" (Differential Loop Modulation) creates gritty, evolving pads and resonant sweeps that modern soundfonts can perfectly preserve.
